A benefit of teuxdeux is that they charge $2 a month with the intention of putting the funds to maintaining the site and not having to sell the company.
Yeah, I was quoting the annual fee. After having a few apps acquired and disappeared (e.g., wunderlist acquired by ms), I liked their strategy of charging just enough to stay independent.
Edit: we're kind of both right. $3/month, or $24/year.
